Auto-Kicking?

Lately, some of the more inactive players in my campaign have been disappearing from the campaign roster. This didn't bother me too much the first time because it was just a pair of guys who hadn't shown up in forever and were probably dropping out, so I guess it saved me the trouble of deciding when enough was enough and removing them manually. This second time, though, it was a guy who had only missed maybe two games and who, last I heard, was still trying to make it. It's possible that all of them just decided to leave, of course, but it's been very unusual for people to actively leave a campaign like that. In my experience, at least, people will usually leave themselves on the roster, never actually checking the campaign, until you remove them, which makes me suspect some kind of new auto-kick feature. Is there an auto-kick feature, and if so, is there a way to turn it off?

I do not believe we have, I will check with the Devs.  It is possible that some of them accidentally hit 'leave campaign' thinking it logged them out of the campaign. Please send me a join link to your campaign.  - Gauss

If you have any Private Messages with the 3rd person, or at least if you remember their Roll20 name, maybe send them a message and ask if they meant to leave the campaign? At the top-right under your name, drop-down menu you can access your PM's. If you hit New Message and start typing the person's Roll20 name it should come up to let you PM them.

I have confirmed that the 3rd player did not intend to leave the campaign (and he has since been invited back into it).
